Description

Activation method of uplink bandwidth part, terminal device and computer storage medium

Technical field

The present invention relates to the field of information processing technologies, and in particular, to an uplink bandwidth part activation method, a terminal device, and a computer storage medium.

Background technique

The system bandwidth supported by NR is much larger than the system bandwidth of LTE up to 20MHz. For some terminals, due to limited capacity, it is not always able to support the entire system bandwidth. In order to improve scheduling efficiency, NR introduces the concept of bandwidth part BWP. In the RRC connection state, the network configures one or more BWPs for the terminal. The BWP mainly includes three parameters: Numerology, center frequency, and bandwidth.

It can be seen that BWP is a concept of frequency domain dimension. At the same time, the existing discussion assumes that at one point in time, the terminal only supports one active BWP. The so-called activation means that the terminal expects to receive signals on the bandwidth specified by the BWP, including data transmission (uplink and downlink), system messages, etc. However, there is currently no regulation on how to activate the BWP on the terminal device side.

Summary of the invention

To solve the above technical problem, an embodiment of the present invention provides an uplink bandwidth part activation method, a terminal device, and a computer storage medium.

Based on the activation control message, it is determined that the uplink BWP is activated and the acknowledgement information is sent to the network side.

The embodiment of the invention provides a terminal device, including:

The communication unit receives an activation control message sent by the network side for the configured uplink bandwidth part BWP; and sends the acknowledgement information to the network side;

Detailed ways

The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

Embodiment 1

An embodiment of the present invention provides an activation method for an uplink bandwidth part, which is applied to a terminal device, as shown in FIG. 1 , and includes:

Step 101: Receive an activation control message sent by the network side for the configured uplink bandwidth part BWP.

Step 102: Based on the activation control message, determine to activate the uplink BWP and send confirmation information to the network side.

In the foregoing step 101, the activation control message may be one uplink BWP in the plurality of uplink bandwidth portions BWP configured by the terminal device, and may of course be multiple uplink BWPs. In other words, the uplink BWP described in step 101 may be a partial uplink BWP in all uplink BWPs configured in the carrier of the terminal device.

Further, the determining, according to the activation control message, determining to activate the uplink BWP and sending the acknowledgement information to the network side includes the following multiple processing situations:

Processing 1,

When the terminal device does not have data to be sent, the corresponding uplink BWP is activated based on the activation control message, and the acknowledgement information for activating the uplink BWP is sent to the network side by the MAC layer control unit CE.

That is, the terminal receives a control message for activating an uplink BWP, and if the terminal has no data to be sent at the current moment, triggering an acknowledgement to activate the MAC CE. The control message for activating an uplink BWP is carried on a PDCCH channel scrambled by a C-RNTI or a PDCCH channel scrambled by a special RNTI, where the special RNTI refers to a dedicated RNTI that activates an uplink BWP, such as UL BWP activation RNTI.

In this scenario, the sending, by the MAC layer control unit CE, the acknowledgment information for activating the uplink BWP to the network side includes:

Transmitting, by the authorization resource indicated in the activation control message, a MAC CE confirming activation of the uplink BWP to the network side;

or,

Activating the MAC CE of the uplink BWP by using the resource transmission configured on the uplink BWP indicated in the activation control message.

That is, the MAC CE can be transmitted on the authorized resource indicated by the control message or on the resource configured on the uplink BWP.

And transmitting, by using the authorized resource indicated in the activation control message, the MAC CE that is activated to activate the uplink BWP to the network side, including:

When the authorization control information is scheduled in the activation control information, and the authorized resource is located on the uplink BWP to be activated, the MAC CE that confirms that the uplink BWP is activated is transmitted on the authorized resource.

That is, the control information (scrambling with C-RNTI) schedules an authorized resource, and the authorized resource is located on the uplink BWP to be activated; if the terminal has no data to be transmitted, the terminal triggers an acknowledgement to activate the MAC CE, The MAC CE transmits on the scheduling resource.

In addition, when the authorization resource is not scheduled in the activation control information, and the index number of the uplink BWP to be activated is indicated in the activation control information, if the uplink BWP to be activated has a configuration resource, the configuration is performed. The resource transmission confirms activation of the MAC CE of the uplink BWP.

That is, the control information (scrambled by the UL BWP activation RNTI) does not schedule an authorization resource, and the control information clearly indicates an uplink BWP to be activated, such as a BWP index; if the uplink BWP to be activated is configured A configured resource (including type 1 and/or type 2) generates an acknowledgement activation MAC CE, and the MAC CE transmits on the configured resource; or generates a configured MAC CE (Configured Grant Confirmation MAC CE). The MAC CE is transmitted on the configuration resource; the LCIDs of the sub-packets corresponding to the two MAC CEs are different;

If the configured uplink resource does not have the configured resource, the feedback information for the activation control information is generated, and the feedback information is transmitted on the physical uplink control channel PUCCH.

Specifically, if the uplink BWP to be activated has no configured resources, the terminal generates a feedback information for the control information, where the feedback information is transmitted on the configured PUCCH resource.

Scene 2

If the terminal has data to be transmitted:

And when the terminal device has data to be sent, and the authorization resource is scheduled in the activation control information, the to-be-sent data is transmitted on the authorized resource.

That is, if the control information (which can be scrambled by C-RNTI) is scheduled, the data to be transmitted is transmitted on the authorized resource.

If the terminal device has data to be transmitted, and the authorized resource is not scheduled in the activation control information, if the configured resource is available, the data to be sent is transmitted on the configured resource; if the configured resource is not provided, A scheduling request is sent in the activated uplink BWP.

Specifically, if the control information (which can be scrambled by the uplink UL bandwidth part BWP activation activation scrambling code RNTI) is not scheduled, if the resource is configured, the terminal transmits the to-be-transmitted data on the configuration resource; if no resource is configured, Then the terminal initiates a scheduling request (SR) on the activated BWP.

It can be seen that, by adopting the foregoing solution, the activation control of one or more uplink BWPs can be performed based on the instruction of the network side, and the terminal sends an acknowledgement message to the network side to notify the network side to determine the uplink that the activation network side indicates that the activation needs to be activated. BWP. In this way, it is possible to standardize the definition of a part of the uplink BWPs when a plurality of uplink BWPs configured on the carrier of one terminal device are configured.

The foregoing activation control message may be one uplink BWP of the plurality of uplink bandwidth parts BWP configured by the terminal device, and may of course be a plurality of uplink BWPs. In other words, the uplink BWP described in step 101 may be a partial uplink BWP in all uplink BWPs configured in the carrier of the terminal device.

Processing 1,

The processing unit 22 activates a corresponding uplink BWP based on the activation control message when the terminal device does not have data to be sent;

The communication unit 21 transmits, by the MAC layer control unit CE, confirmation information for activating the uplink BWP to the network side.
